Question

这是我编写的代码段

MainPage.py

from flask import Flask, render_template,url_for,request, redirect
from form import SearchForm
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secretkey1234'


@app.route("/")
@app.route("/home", methods=['GET', 'POST'])
def home():
    forms = SearchForm()
    return render_template('home.html', title='Home', forms=forms)

@app.route("/about")
def about():
    return render_template('about.html', title='About')


if __name__ == '__main__':
    app.run(debug=True)

form.py

from flask_wtf import FlaskForm
import Get_Test_Suite
from wtforms.fields import SelectField, SubmitField
from wtforms.fields.html5 import DateField
from wtforms.validators import DataRequired


class SearchForm(FlaskForm):
    test_suite_list = Get_Test_Suite.get_test_suite()
    suite_list = []
    for i in test_suite_list:
        suite_list.append((i, i))
    test_suite_selected = SelectField('Test Suite Name', choices=suite_list)

    test_module_list = Get_Test_Suite.get_module_name()
    module_list = []
    for j in test_module_list:
        module_list.append((j, j))
    test_module_selected = SelectField('Test Module Name', choices=module_list,validators=[DataRequired()])
    date_selected = DateField('Date', format='%m-%d-%Y')
    status = SelectField('Status', choices=[('Active', 'Active'), ('Closed', 'Closed')])
    submit = SubmitField('Submit')

home.html

{% extends "layouts.html" %}
{% block content %}
   <div class = "content-section">
       <form method="POST" action="">
           {{forms.hidden_tag()}}
           <fieldset class="form-group">

我正在home.html中创建许多下拉列表如何获得用户从每个下拉列表中选择的数据并进行打印？我正在尝试创建一个用户友好的Web应用程序，用户将在其中从下拉列表中选择值，然后该应用程序将从数据库中相应地获取数据。

Answer 1

您是否尝试过将“选择”转换成字典？然后，您可以获取密钥表单数据的值。也许是这样的（对于您的“状态” SelectField）：
value = dict(form.status.choices).get(form.status.data)

Answer 2

我确定您已找到解决方案，但适用于下一代。您需要在选择标签中插入值的名称，而不是在选项标签中。

示例：

<select name="sServer">

  {% for server in servers %}
  <option  value="{{server}}">{{server}}</option>
  {% endfor %}

</select>

如何从python Flask WTF中的SelectField获取用户选择的值？
